ROCKING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 268,757, dated December5, 1882.l

' Application filed September 8, 1882. (No model.)

To all whom it may concern:

f Be it known that I, FRIEDERIOH VOGEL, a ctfzen of the United States,residing at the city of New York, State ot' New York, have invented newand useful improvements in `Rocking- (ilhairs, of which thefollowing isa specification.

This invention relates to that class of rocking-chairs in which thechair proper rests and rocks upon a base portion, and the said partsconnected together by means of warms and springs, whereby the playor'rnovement of the chair upon the base is controlled and limited. Theobject of my invention is to improve the connecting devices so thatwhile the same shall be ot' cheap and simple construction they willefiicientlyand properly perform their functions and the chair as a Wholebe much improved thereby; and theinvention consists in the combination,with a chair proper and a base or support, of a pivoted slotted link,through the slot of which a pin on the base projects, and a springcoiled around said pin, the ends of which are secured to depending armspivoted with the slotted link to the chair-runners, substantially in theVmanner and for the purpose- ,hereinafter set forth.

1n the annexed drawings, Figure l is an ele- "vation ot a rocking-chairto which my inven- `tion is applied, and Fig. 2 1s a crosssection ot'the saine on tbe line w y.

Referring to the drawings, A designates the chair proper, which restsand rocks upon the base or support B. These parts may be of any ordinaryor suitable construction.

d is a link slotted at its lower end, through which slot the pin c,secured to the plate b, passes. This plate is securely attached to thebase B by means of screws or otherwise. The link d at its upper end ispivoted to the plate a of the chair-runners, and there are also pivotedat the same point the arms c c, `depending' upon each side ot' the link,as shown, the lower ends of the said arms being bent into hooks toreceive the endsfof the spring s. This spring is coiled spirally aroundthe pin and. serves to keep the arms c c at the proper angle. It alsoserves to bring the chair in its proper vertical position. The pin e isby preference covered by a rubber tube, t,.a washer, w, being placedbetween said tube and the link d.

Instead ofmaking the arms c c separate, they may be made in one piece,if desired, in this case forming a bell-crank lever. K

lt will be seen that in using the chair its movement forward or backwardis limited and controlled by the link d, the pin e, working in the slotin said link, preventing too great a movement in either direction bystriking against the upper or lower end of the slot. The spring s, beingattached to the arms c c, as before described, tends to bring the chairto a vertical position after being moved either backward or forward, andthus renders the rocking of the chair easy and agreeable.

Having thus described my invention, what I claim is- The combination,with the chair A and its base B, ot the longitudinally-slotted link d,pivoted to the chair and receiving in its slot a pin which is attachedto the base, and the arms c c, pivoted together at their upper ends totho chair and at their lower ends connected with the ends of aspringwhich is coiled around the pin c, substantially as described.

In testimony whereof I have hereunto set my 7 hand in the presence oftwo subscribing Witnesses. v
